摘要：
The purpose of this study is to investigate observational features of Brans-Dicke wormholes. The energy flux from accretion onto a Brans-Dicke wormhole and the so-called "maximum impact parameter" are studied (the later might allow to observe light sources through a wormhole throat). The computed values were compared with the corresponding ones for GR-wormholes and Schwarzschild black holes. Brans-Dicke wormholes are shown to be quasi-Schwarzschild objects and should differ from GR wormholes by about one order of magnitude in the accretion energy flux.
